Wendy's went after McDonald's again on Tuesday, using an Avenger's meme for another pot shot about frozen beef. Earlier this year, McDonald's announced that all locations would use fresh beef for Quarter Pounders and Signature Crafted burgers by the end of the year. That, of course, leaves many burgers, including the Big Mac, to be made with frozen meat.

Let's keep this spoiler free and say the meme Wendy's is using is about the end of Avengers: Infinity War. (If you want to know details, here's more about that meme and the ending of Infinity War.) The moral is that Wendy's will take any opportunity it can to remind it uses fresh beef and its competitors aren't always doing the same.
